The microcomputer hardware system is divided into two parts: host and external devices. What does the host include?

The microcomputer hardware system is divided into two parts: the host and the external device. The host includes the arithmetic unit, the memory and the controller. The main function of the arithmetic unit is to calculate and process data and information. The memory can both receive and Saving data can also provide data to other components. By integrating and analyzing relevant data and information, the controller can allow various components of the computer to complete instructions in an orderly manner.

The microcomputer hardware system is divided into two parts: the host and the external equipment. The host includes the arithmetic unit, Memory and controller

• Operator, the main function is to calculate and process data and information

• Controller, through integration Analyzing relevant data and information allows the various components of the computer to complete instructions in an orderly manner

• Memory is the memory storage component in the computer, which can not only accept and save data, but also Providing data to other components

The microcomputer hardware system consists of two parts: the host computer and external devices.

The host consists of a computer, a central processing unit and a memory. External devices input devices and output devices, namely keyboards, mice, printers, scanners and other devices.

A computer without any software installed is called a bare metal computer. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers and embedded computers. More advanced computers include biological computers, photon computers, quantum computers, etc.

1. Hardware composition (input device, output device, memory, arithmetic unit, controller)

Input device: mouse , keyboard, light pen, scanner, microphone, digital camera, webcam, tablet.

Output device: The computer processes the information and expresses it in a form that we can recognize, such as: monitor, printer, plotter, audio, projector memory, hard disk, optical drive, USB flash drive: arithmetic operations, logical operations .

Controller: If instructions are fetched from the memory, the controller and computer are integrated into the CPU to control the coordinated operation of various parts of the computer.

2. Software composition Software definition: the general term for programs and related documents and materials Software classification: system software (the use and management of computer software) and application software (software specially designed for a certain application)

Commonly used system software includes: operating system, database management system and programming language. Commonly used application software includes: auxiliary teaching software, auxiliary design software, word processing software, information management software and automatic control software. .
